A large reason for the halt of sales, says the memo, is Microsoft has a "new policy" of not supporting dual-OS products. Patrick Moorhead, principal analyst at Moor Insights and Strategy, told us in January that "Microsoft does not want [dual-OS devices] to happen," and now tells The Wall Street Journal that "Google wants all-Android devices" as well.

While I doubt many consumers are waiting for dual-boot devices, I personally would love to have a tablet that boots both Android and Windows 8. It's a shame that's not going to happen.

I do wonder why the policy is proclaimed to be "new". Microsoft has always fought dual-booting products tooth and nail.
